Chapter 2: Troubleshooting Guidelines

2-6 Troubleshooting Guide

5. If the problem has not been remedied, proceed as follows:

a. Repeat steps in Sections 2.2, 2.3, and 2.4 until a solution is found within a reasonable period of time.

The possibilities should narrow down until either a solution is found or the problem is found to be

unsolvable by the persons applying this method.

b. Depending on the severity or urgency of the problem, call in other experts such as Cabletron Systems

Technical Support.

2.5 Implement and Document Fixes

Document everything! Whether or not your effort ﬁxed the problem, document your efforts to help prevent

repeating your steps or for future reference in case you run into the problem again. The documentation is

especially helpful for troubleshooting intermittent problems.

2.6 Isolate the Problem

The following steps provide a guide to help isolate the problem to a particular part of the network:

1. To help determine if there is a problem, when it started, and if it’s a critical network situation, consider the

following.

a. Is the problem on all of the network?

b. Is it critical that the network remain up and running without interruption?

If so, refer to the Service Contract for spares coverage and other service support information.

c. What is the network bounded by?

- Is it local?

- Is it bridged?

- What distance does it cover?

- Is the network a WAN?

d. Is the problem conﬁned to one portion of the network?

- You can remove components such as MIMs to see if the problem goes away.

e. Does that portion have any well-deﬁned boundaries, such as bridges, routers, ATM switches or types of

workgroups?

f. Is the problem conﬁned to one hub or workgroup, software application, or protocol?

g. Have there been any additions, changes, or upgrades made to the network within the last month or so?

If so, what, and what kind of consequences could they have on the network, and how could they affect

the current situation?
